2.4 GHz WLAN Front-End Module
The SKY85333-11 is a highly integrated, 2.4 GHz front-end
module (FEM) incorporating a 2.4 GHz single-pole, double-throw
(SPDT) transmit/receive (T/R) switch, a 2.4 GHz high-gain lownoise
amplifier (LNA) with bypass, and a 2.4 GHz power amplifier
(PA) intended for high-power 802.11ax applications and systems.
The LNA and PA disable functions ensure low leakage current in the off mode. An integrated logarithmic power detector is included to provide closed-loop power control over 25 dB of dynamic range. A digital pre-distortion (DPD) coupler is provided to further improve the linearity of the FEM.
The device is provided in a compact, 24-pin 3 x 5 mm Land Grid Array (LGA) package, which may reduce the front-end board space by more than 50 percent.
